A fresh clone of the repo + vagrant up centos-6 fails.

The issue appears to be missing EPEL repos from CentOS. However when you look at the output there is a warning line:

[2013-12-16T22:11:48+00:00] WARN: An Omnibus platform recipe does not exist for the platform_family: rhel

Which makes no sense - the pulled in omnibus cookbook version from the Berkshelf.lock file is 1.0.8. And the 1.0.8 version of omnibus does include a rhel recipe: https://github.com/opscode-cookbooks/omnibus/tree/1.0.8/recipes

Just for fun I bumped the omnibus-cookbook version to 1.1.0 and it failed with the same error (and warning about a missing platform recipe for rhel".

I tried to use version 1.2.2 of omnibus but it keeps failing on an rbenv problem trying to interact with git - but that is something to do with my ISP and git which has been causing my lots of problems all day.

On the 1.0.8 attempt I went into the vm and ran these commands:

[vagrant@sample-python-app-omnibus-build-lab ~]$ sudo rpm --import http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6
[vagrant@sample-python-app-omnibus-build-lab ~]$ sudo rpm -Kih http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

And then did vagrant provision centos-6 and it ran fine and built the rpm.

Found the issue. On my machine it was pulling in version 3.0 of the yum cookbook (which has lots of breaking changes - like, no epel recipe). The try/rescue in the omnibus cookbook was trying to import the platform family recipe but was hiding the actual error (found it when I turned on debug logging):

[2013-12-17T06:19:17+00:00] DEBUG: Found recipe default in cookbook omnibus

...
[Berkshelf] Using yum (3.0.0)
...

I added a version constraint on yum to < 3.0 in #2 which solves the issue for me.
